Question

Six frontier AI models put this at 44% by 15 Mar 2027. Full reasoning from every model.

44% — the median of 6 frontier models, resolving by 2027-03-15.

Answer

Gemini (Google): 26% — A 10% drawdown requires a sharp macro shock or earnings rerating within an unusually tight 3.5-month window. Historically, 10% corrections occur roughly once every 1.5 to 2 years, yielding an unconditional ~20-25% probability over 3.5 months. Elevated index concentration in mega-cap tech increases downside fragility if Q3 earnings disappoint or rate cuts stall. A sustained surge in oil above $95 or a rapid labor market deterioration by November would push odds above 45%.

Answer

Claude (Anthropic): 62% — Whether valuation stretch, rate shocks, or AI-capex unwind trigger a 10% drawdown before year-end 2026. Base rate: S&P 10%+ corrections occur roughly once every 1-2 years historically, and none has occurred since the current window began. Elevated valuations, concentrated AI-driven gains, and rate/policy uncertainty raise odds versus a calm-market baseline. A sustained soft-landing with steady earnings growth and Fed easing through 2026 would keep this from resolving true.

Answer

GPT (OpenAI): 71% — A 10% drawdown is common over a 15-month horizon, and elevated valuation leaves little cushion for shocks. The S&P 500 has historically had 10% corrections roughly every 1–2 years, putting the base rate above even over this window. There is no single decision-maker; a growth, inflation, earnings, or geopolitical shock can trigger risk repricing before Dec. 31. A durable Fed easing cycle and continued earnings upgrades without an inflation rebound would most reduce the odds.

Answer

Grok (xAI): 23% — Whether any peak-to-trough drop hits 10% in the remaining 106 days. Only the Fed, earnings, or an exogenous shock can force a 10% slide from the Sep high before 31 Dec. Historically a 10% correction arrives ~once every 18 months, implying ~20% odds in a 3.5-month window; stretched 2026 valuations lift that slightly. A VIX spike above 30 or a 50-bp unexpected rate move would most raise the probability.

Answer

DeepSeek (DeepSeek): 22% — A 10% drawdown needs a catalyst to break a market that has spent 2026 grinding higher on AI earnings. Since 1950, a 10% correction has occurred in roughly 60% of calendar years, but the window here is only ~3.5 months, not a full year. The Fed's remaining 2026 meetings (Sep 16, Oct 28, Dec 9) are the main scheduled shocks; a hawkish surprise or AI-capex disappointment would be the trigger. Current positioning is complacent after a strong 2026, so a 10% drop would likely need a credit event or earnings miss, not just valuation fatigue.

Answer

Qwen (Alibaba): 72% — Corrections of 10%+ occur roughly once every 18 months on average; we have ~3.5 months left in 2026. Since 1950 the S&P 500 has seen a 10%+ drawdown in about 55-60% of calendar years, so base rate alone is ~55% for any given year. With only ~3.5 months remaining, the window is short, but current valuations (forward P/E ~22x) and concentration risk in mega-cap tech sit above historical norms… A single macro shock—Fed policy error, credit event, or geopolitical escalation—could trigger it quickly; the main scenario keeping it below 72 is a sustained melt-up…
